Mpk organic alternative bloom booster (mpk 0-52-34)

I’m trying to incorporate an organic bloom booster like Mono Potassium Phosphate (mpk 0-52-34) do you have any suggestions?

Or should i just mix Potassium Sulfate 0.0.50 and Fish Bone Powder 4-20-0 together? Or just double up in the dose of liquid bone meal 0.14.0?
